Water birth: a systematic review and meta-analysis of maternal and neonatal outcomes.

OBJECTIVE: This systematic review and meta-analysis aimed to conduct a thorough and contemporary assessment of maternal and neonatal outcomes associated with water birth in comparison with land-based birth. DATA SOURCES: We conducted a comprehensive search of PubMed, EMBASE, CINAHL, and gray literature sources, from inception to February 28, 2023. STUDY ELIGIBILITY CRITERIA: We included randomized and nonrandomized studies that assessed maternal and neonatal outcomes in patients who delivered either conventionally or while submerged in water. METHODS: Pooled unadjusted odds ratios with 95% confidence intervals were calculated using a random-effects model (restricted maximum likelihood method). We assessed the 95% prediction intervals to estimate the likely range of future study results. To evaluate the robustness of the results, we calculated fragility indices. Maternal infection was designated as the primary outcome, whereas postpartum hemorrhage, perineal lacerations, obstetrical anal sphincter injury, umbilical cord avulsion, low Apgar scores, neonatal aspiration requiring resuscitation, neonatal infection, neonatal mortality within 30 days of birth, and neonatal intensive care unit admission were considered secondary outcomes. RESULTS: Of the 20,642 articles identified, 52 were included in the meta-analyses. Based on data from observational studies, water birth was not associated with increased probability of maternal infection compared with land birth (10 articles, 113,395 pregnancies; odds ratio, 0.93; 95% confidence interval, 0.76-1.14). Patients undergoing water birth had decreased odds of postpartum hemorrhage (21 articles, 149,732 pregnancies; odds ratio, 0.80; 95% confidence interval, 0.68-0.94). Neonates delivered while submerged in water had increased odds of cord avulsion (10 articles, 91,504 pregnancies; odds ratio, 1.75; 95% confidence interval, 1.38-2.24) and decreased odds of low Apgar scores (21 articles, 165,917 pregnancies; odds ratio, 0.69; 95% confidence interval, 0.58-0.82), neonatal infection (15 articles, 53,635 pregnancies; odds ratio, 0.64; 95% confidence interval, 0.42-0.97), neonatal aspiration requiring resuscitation (19 articles, 181,001 pregnancies; odds ratio, 0.60; 95% confidence interval, 0.43-0.84), and neonatal intensive care unit admission (30 articles, 287,698 pregnancies; odds ratio, 0.56; 95% confidence interval, 0.45-0.70). CONCLUSION: When compared with land birth, water birth does not appear to increase the risk of most maternal and neonatal complications. Like any other delivery method, water birth has its unique considerations and potential risks, which health care providers and expectant parents should evaluate thoroughly. However, with proper precautions in place, water birth can be a reasonable choice for mothers and newborns, in facilities equipped to conduct water births safely.

Neonatal outcomes after water birth: A retrospective cohort study.

OBJECTIVE: To compare neonatal outcomes between water births, births with immersion only during labour, and births in which immersion was never used. METHODS: A retrospective cohort study was performed including mother-baby dyads attended between 2009 and 2019 at the Hospital do Salnés regional hospital (Pontevedra, Spain). These women were categorised into 3 groups: water birth; immersion only during dilation; and women who never used immersion. Several sociodemographic-obstetric variables were studied and the main outcome was the admission of the neonate to the intensive care unit (NICU). Permission was obtained from the responsible provincial ethics committee. Descriptive statistics were used and between-group comparisons were performed using variance for continuous variables and chi-square for categorical variables. Multivariate analysis was performed with backward stepwise logistic regression and incidence risk ratios with 95%CI were calculated for each independent variable. Data were analysed using IBM SPSS® statistical software. RESULTS: A total of 1191 cases were included. 404 births without immersions; 397 immersions only during the first stage of labor; and 390 waterbirths were included. No differences were found in the need to transfer new-borns to a NICU (p = .735). In the waterbirth cohort, neonatal resuscitation (p < .001, OR: 0,1), as well as respiratory distress (p = .005, OR: 0,2) or neonatal problems during admission (p < .001, OR: 0,2), were lower. In the immersion only during labor cohort, less neonatal resuscitation (p = .003; OR: 0,4) and respiratory distress (p = .019; OR: 0,4) were found. The probability of not breastfeeding upon discharge was higher for the land birth cohort (p < .001, OR: 0,4). CONCLUSIONS: The results of this study indicated that water birth did not influence the need for NICU admission, but was associated with fewer adverse neonatal outcomes, such as resuscitation, respiratory distress, or problems during admission.

[Care in a natural birth center and due compliance with national guidelines]. / O cuidado na casa de parto e sua conformidade com as diretrizes nacionais.

The scope of this article is to analyze the compliance of the care offered by Casa de Parto David Capistrano Filho-RJ with the recommendations of the National Guidelines for Care in Natural Childbirth. It involved a descriptive cross-sectional study with 952 observations, from 2014 to 2018. This included analysis of compliance using a judgment matrix and then classified as total compliance (≥75.0%), partial compliance (50.0%-74.9%), incipient compliance (49.9%-25.0%) and non-compliance (less than 24.9%). The results of the judgment matrix show that care in the aspects of labor, delivery and newborn care is in full compliance with the recommendations of the Guidelines. The care at the Casa de Parto Birth Center, conducted by obstetric nurses, follows the recommendations of the national guidelines, and has been seen to incorporate a de-medicalized, personalized form of care, which respects the physiology of childbirth. They also develop a model of their own technologies of care, constituting non-invasive technologies of obstetric nursing care.

The perfect birth: a content analysis of midwives' posts about birth on Instagram.

BACKGROUND: There is limited research into how midwives use social media within their professional role. Small pilot studies have explored the introduction of social media into maternity practice and teaching but there is little evidence around how midwives use social media professionally. This is important as 89% of pregnant women turn to social media for advice during pregnancy, and how midwives use social media could be influencing women, their perception of birth and their decision making. METHODS: AIM: To analyse how popular midwives portray birth on the social media platform Instagram. This is an observational mixed methods study using content analysis. Five 'popular' midwives from each country (UK, New Zealand, USA and Australia) were identified and their posts about birth collated from a one-year period (2020-21). Images/videos were then coded. Descriptive statistics enabled comparison of the posts by country. Categorisation was used to analyse and understand the content. RESULTS: The study identified 917 posts from the 20 midwives' accounts, containing 1216 images/videos, with most coming from USA (n = 466), and UK (n = 239), Australia (n = 205) and New Zealand (n = 7) respectively. Images/videos were categorised into 'Birth Positivity', 'Humour', 'Education', 'Birth Story' and 'Advertisement'. Midwives' portrayals of birth represented a greater proportion of vaginal births, waterbirths and homebirths than known national birth statistics. The most popular midwives identified mainly had private businesses (n = 17). Both the midwives and women portrayed in images were primarily white, demonstrating a disproportionate representation. CONCLUSION: There is a small midwifery presence on Instagram that is not representative of the broader profession, or the current picture of midwifery care. This paper is the first study to explore how midwives are using the popular social media platform Instagram to portray birth. It provides insight into how midwives post an un-medicalised, low risk representation of birth. Further research is recommended to explore midwives' motivation behind their posts, and how pregnant and postnatal women engage with social media.

Spiritual Experiences of Portuguese Women Who had a Water Birth.

This study aimed to understand the significance of spirituality to Portuguese women who had a water birth. In-depth interviews, using a semi-structured questionnaire, were conducted with 24 women who experienced water birth at the hospital or home. Results were analyzed from a narrative interpretation perspective. Three spirituality-related categories emerged: (1) Beliefs and connections with the body; (2) Spirituality: integration of being a woman and transformation during birth; and (3) Spirituality as wisdom, intuition, or the sixth sense. Spirituality was perceived in women's faith and beliefs in a superior being that helped them manage the unpredictability and uncontrollability of giving birth.

Midwives' Perception Regarding Conditions Influencing the Implementation of the Natural Childbirth Promotion Program in Iran: A Qualitative Study.

Background: In Iran, the Natural Childbirth Promotion Program (NCPP) has been implemented as a component of the Health Transformation Plan (HTP) since 2014 and as an attempt to encourage natural childbirth practices and reduce cesarean section rates. The purpose of this qualitative study was to explore the perceptions of midwives about conditions influencing the implementation of NCPP. Methods: In this qualitative study, data were collected through 21 in-depth semi-structured individual interviews with expert midwives who were selected using purposive sampling mainly from one medical university in Eastern Iran from October 2019 to February 2020. Based on the framework method as a thematic analysis approach, the data were analyzed manually. To enhance the rigor of the study, we followed Lincoln and Guba's criteria. Results: Data analysis yielded 546 open codes. After the codes were reviewed and similar codes were removed, there remained 195 codes. Further analysis led to extraction of 81 sub-sub themes, 19 sub-themes, and eight main themes. These themes included: Responsive staff; Characteristics of the parturient; Recognition of midwifery role; Teamwork; The birthing environment; Effective management; Institutional and social context; and Social education. Conclusion: Based on the perceptions of the studied midwives, the success of the NCPP is guaranteed by a set of conditions identified in this study. In practice, these conditions are complementary and interrelated, and they cover a wide range of staff and parturient characteristics to the social context. It seems that effective implementation of the NCPP also calls for the accountability of all stakeholders, from policymakers to maternity care providers.

A prospective cohort study comparing neonatal outcomes of waterbirth and land birth in an Australian tertiary maternity unit.

BACKGROUND: Maternal preference for warm water immersion (WWI) and waterbirth is increasing, but adoption into obstetric guidelines and clinical practice remains limited. Concerns regarding safety and a paucity of evidence have been cited as reasons for the limited adoption and uptake. AIM: The aim was to investigate maternal and neonatal outcomes after WWI and/or waterbirth compared with land birth. MATERIALS AND METHODS: A prospective cohort study was conducted in an Australian public maternity hospital between 2019 and 2020. Maternal and neonatal outcomes for 1665 women who had a vaginal birth were studied. Primary outcome was admission to the neonatal unit (NNU). Secondary outcomes included neonatal antibiotic administration, maternal intrapartum fever, epidural use and perineal injury. Multivariate logistical regression analyses compared the outcomes between three groups: waterbirth, WWI only and land birth. RESULTS: NNU admissions for a suspected infectious condition were significantly higher in the land birth group (P = 0.035). After accounting for labour duration, epidural use and previous birth mode, no significant difference was detected between groups in the odds of NNU admission (P = 0.167). No babies were admitted to NNU with water inhalation or drowning. Women birthing on land were more likely to be febrile (2 vs 0%; P = 0.007); obstetric anal sphincter injury and postpartum haemorrhage were similar between groups. Regional analgesia use was significantly lower in the WWI group compared to the land birth group (21.02 vs 38.58%; P = <0.001). There was one cord avulsion in the waterbirth group (0.41%). CONCLUSION: Maternal and neonatal outcomes were similar between groups, with no increased risk evident in the waterbirth and WWI groups.

The practicalities of adapting UK maternity clinical information systems for observational research: Experiences of the POOL study.

Background: Using routinely collected clinical data for observational research is an increasingly important method for data collection, especially when rare outcomes are being explored. The POOL study was commissioned to evaluate the safety of waterbirth in the UK using routine maternity and neonatal clinical data. This paper describes the design, rationale, set-up and pilot for this data linkage study using bespoke methods. Methods: Clinical maternity information systems hold many data items of value for research purposes, but often lack specific data items required for individual studies. This study used the novel method of amending an existing clinical maternity database for the purpose of collecting additional research data fields. In combination with the extraction of existing data fields, this maximised the potential use of existing routinely collected clinical data for research purposes, whilst reducing NHS staff data collection burden.Wellbeing Software®, provider of the Euroking® Maternity Information System, added new study specific data fields to their information system, extracted data from participating NHS sites and transferred data for matching with the National Neonatal Research Database to ascertain outcomes for babies admitted to neonatal units. Study set-up processes were put in place for all sites. The data extraction, linkage and cleaning processes were piloted with one pre-selected NHS site. Results: Twenty-six NHS sites were set-up over 27 months (January 2019 - April 2021). Twenty-four thousand maternity records were extracted from the one NHS site, pertaining to the period January 2015 to March 2019. Data field completeness for maternal and neonatal primary outcomes were mostly acceptable. Neonatal identifiers flowed to the National Neonatal Research Database for successful matching and linkage between maternity and neonatal unit records. Discussion: Piloting the data extraction and linkage highlighted the need for additional governance arrangements, training at NHS sites and new processes for the study team to ensure data quality and confidentiality are upheld during the study. Amending existing NHS electronic information systems and accessing clinical data at scale, is possible, but continues to be a time consuming and a technically challenging exercise.

The Role of Midwives in the Course of Natural Childbirth-Analysis of Sociodemographic and Psychosocial Factors-A Cross-Sectional Study.

BACKGROUND: An important role in the course of natural childbirth is played by midwives, who should effectively work on relieving pain. This study aims to present the opinions of midwives on non-pharmacological methods of relieving labor pain; the frequency of their use and reasons for their abandonment; and the relationship between the use of non-pharmacological methods of relieving labor pain and perceived job satisfaction, burnout, and self-efficacy of the midwife. METHODS: The study was conducted online, with the participation of 135 Polish midwives working in the delivery room. The author's survey questionnaire, the Generalized Self-Efficacy Scale (GSES), the LBQ Burnout Questionnaire, and the Scale of Job Satisfaction were used. RESULTS: Among the surveyed midwives, 77% use vertical positions in work with a patient giving birth. Almost all respondents consider vertical positions as an example of a non-pharmacological method of relieving labor pain; those with master's degree felt more prepared for their use (p = 0.02). The most common reason for abandoning their use was disagreement on the part of co-workers (p = 0.005). An association was observed between the use of vertical positions and the level of burnout (p = 0.001) and a significant correlation between preparation for their use and self-efficacy assessment, burnout, and job satisfaction. CONCLUSION: Our research shows that it would be important to conduct additional training on the use of non-pharmacological methods to relieve labor pain and to present their benefits. In contrast to other research results, our results showed that midwives feel well prepared to use these methods; however, similar to other research, we found that they often feel disagreement from colleagues and a lack of support from their leaders. The use of vertical positions is related to burnout.

Systematic review and meta-analysis to examine intrapartum interventions, and maternal and neonatal outcomes following immersion in water during labour and waterbirth.

OBJECTIVES: Water immersion during labour using a birth pool to achieve relaxation and pain relief during the first and possibly part of the second stage of labour is an increasingly popular care option in several countries. It is used particularly by healthy women who experience a straightforward pregnancy, labour spontaneously at term gestation and plan to give birth in a midwifery led care setting. More women are also choosing to give birth in water. There is debate about the safety of intrapartum water immersion, particularly waterbirth. We synthesised the evidence that compared the effect of water immersion during labour or waterbirth on intrapartum interventions and outcomes to standard care with no water immersion. A secondary objective was to synthesise data relating to clinical care practices and birth settings that women experience who immerse in water and women who do not. DESIGN: Systematic review and meta-analysis. DATA SOURCES: A search was conducted using CINAHL, Medline, Embase, BioMed Central and PsycINFO during March 2020 and was replicated in May 2021. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Primary quantitative studies published in 2000 or later, examining maternal or neonatal interventions and outcomes using the birthing pool for labour and/or birth. DATA EXTRACTION AND SYNTHESIS: Full-text screening was undertaken independently against inclusion/exclusion criteria in two pairs. Risk of bias assessment included review of seven domains based on the Robbins-I Risk of Bias Tool. All outcomes were summarised using an OR and 95% CI. All calculations were conducted in Comprehensive Meta-Analysis V.3, using the inverse variance method. Results of individual studies were converted to log OR and SE for synthesis. Fixed effects models were used when I2 was less than 50%, otherwise random effects models were used. The fail-safe N estimates were calculated to determine the number of studies necessary to change the estimates. Begg's test and Egger's regression risk assessed risk of bias across studies. Trim-and-fill analysis was used to estimate the magnitude of effect of the bias. Meta-regression was completed when at least 10 studies provided data for an outcome. RESULTS: We included 36 studies in the review, (N=157 546 participants). Thirty-one studies were conducted in an obstetric unit setting (n=70 393), four studies were conducted in midwife led settings (n=61 385) and one study was a mixed setting (OU and homebirth) (n=25 768). Midwife led settings included planned home and freestanding midwifery unit (k=1), alongside midwifery units (k=1), planned homebirth (k=1), a freestanding midwifery unit and an alongside midwifery unit (k=1) and an alongside midwifery unit (k=1). For water immersion, 25 studies involved women who planned to have/had a waterbirth (n=151 742), seven involved water immersion for labour only (1901), three studies reported on water immersion during labour and waterbirth (n=3688) and one study was unclear about the timing of water immersion (n=215).Water immersion significantly reduced use of epidural (k=7, n=10 993; OR 0.17 95% CI 0.05 to 0.56), injected opioids (k=8, n=27 391; OR 0.22 95% CI 0.13 to 0.38), episiotomy (k=15, n=36 558; OR 0.16; 95% CI 0.10 to 0.27), maternal pain (k=8, n=1200; OR 0.24 95% CI 0.12 to 0.51) and postpartum haemorrhage (k=15, n=63 891; OR 0.69 95% CI 0.51 to 0.95). There was an increase in maternal satisfaction (k=6, n=4144; OR 1.95 95% CI 1.28 to 2.96) and odds of an intact perineum (k=17, n=59 070; OR 1.48; 95% CI 1.21 to 1.79) with water immersion. Waterbirth was associated with increased odds of cord avulsion (OR 1.94 95% CI 1.30 to 2.88), although the absolute risk remained low (4.3 per 1000 vs 1.3 per 1000). There were no differences in any other identified neonatal outcomes. CONCLUSIONS: This review endorses previous reviews showing clear benefits resulting from intrapartum water immersion for healthy women and their newborns. While most included studies were conducted in obstetric units, to enable the identification of best practice regarding water immersion, future birthing pool research should integrate factors that are known to influence intrapartum interventions and outcomes. These include maternal parity, the care model, care practices and birth setting. PROSPERO REGISTRATION NUMBER: CRD42019147001.

Impact of waterbirth on post-partum hemorrhage, genital trauma, retained placenta and shoulder dystocia: A systematic review and meta-analysis.

BACKGROUND: There is insufficient high-quality evidence to either support or discourage water birth (WB). OBJECTIVES: To examine different maternal complications of WB compared to standard land birth (LB). The primary outcomes were postpartum hemorrhage and genital trauma. The secondary outcome included the risk of retained placenta and shoulder dystocia. METHODS: We searched the electronic databases including PubMed, MEDLINE, Embase, Scopus, EBSCO. In addition, we searched in Google Scholar and ClinicalTrials.gov. The pooled results were used to evaluate the association between WB and obstetric outcomes. This systematic review (SR) was reported according to PRISMA statement 2020. Statistical meta-analyses were performed using Cochrane RevMan version 5.4 software (http://www.cochrane.org). RESULTS: This systematic review included 22 studies (20 observational studies and 2 RCT). The pooled results showed lower risk of major PPH compared to the LB group (OR = 0.76, 95% CI: 0.66-0.89), no significant difference (OR: 0.94, 95% CI: 0.50-1.78) in the incidence of minor PPH (500-1000 mL blood loss) between WB and LB, no significant difference in the rate of third- and fourth-degree lacerations (OR = 0.87, 95% CI: 0.71-1.07) and in the incidence of retained placenta (OR = 1.30, 95% CI: 0.50-3,35), fewer shoulder dystocia for WB (OR = 0.42, 95% CI: 0.35-0.50). However, compared with the LB group, the rate of first-second-degree tears in the WB group increased by 45% (OR = 1.45, 95% CI: 1.16-1.81). CONCLUSION: We support ACOG guidelines recommendation for further RCT to assess the impact of water immersion during delivery on maternal outcomes.

Waterbirths were associated with low pain relief during delivery, high breastfeeding success and healthy newborn infants.

AIM: Our aim was to compare the outcomes of waterbirths and conventional births in a Finnish hospital setting for the first time. METHODS: This retrospective study compared waterbirths with conventional low-risk deliveries from September 2018 to March 2021 at a level-two hospital in Finland. Cases and controls were collected from the patient records database. RESULTS: The study comprised 78 waterbirths and 1623 matched conventional births. Mothers in the waterbirth group only required a quarter of the amount of pain medication required by those in the control group. Babies born in water had slightly lower birth temperatures than those born conventionally (36.6 versus 36.8°C). Umbilical cord artery and vein pH were slightly higher in the waterbirth group than in the control group (artery 7.31 versus 7.28 and vein 7.38 versus 7.35). The Apgar scores did not differ. Hospital stays were shorter in the waterbirth group than in the conventional birth group (1.90 versus 2.33 days). Babies in the waterbirth group were significantly less likely to require formula than those in the conventional birth group during their hospital stay. CONCLUSION: Waterbirth decreased the requirement for maternal pain medication and favoured greater breastfeeding and earlier discharge. Prospective studies must confirm these findings.

Is a randomized controlled trial of waterbirth possible? An Australian feasibility study.

BACKGROUND: The safety of waterbirth is contested because of the lack of evidence from randomized trials and conflicting results. This research assessed the feasibility of a prospective study of waterbirth (trial or cohort). METHODS: We conducted a prospective cohort study at an Australian maternity hospital. Eligible women with uncomplicated pregnancies at 36 weeks of gestation were recruited and surveyed about their willingness for randomization. The primary midwife assessed waterbirth eligibility and intention on admission in labor, and onset of second stage. Primary outcomes measured feasibility. Intention-to-treat analysis, and per-protocol analysis, compared clinical outcomes of women and their babies who intended waterbirth and nonwaterbirth at onset of second stage. RESULTS: 1260 participants were recruited; 15% (n = 188) agreed to randomization in a future trial. 550 women were analyzed by intention-to-treat analysis: 351 (waterbirth) and 199 (nonwaterbirth). In per-protocol analysis, 14% (n = 48) were excluded. Women in the waterbirth group were less likely to have amniotomy and more likely to have water immersion and physiological third stage. There were no differences in other measures of maternal morbidity. There were no significant differences between groups for serious neonatal morbidity; four cord avulsions occurred in the waterbirth group with none in the landbirth group. An RCT would need approximately 6000 women to be approached at onset of second stage. CONCLUSIONS: A randomized trial of waterbirth compared with nonwaterbirth, powered to detect a difference in serious neonatal morbidity, is unlikely to be feasible. A powered prospective study with intention-to-treat analysis at onset of second stage is feasible.

Waterbirth: current knowledge and medico-legal issues.

Water immersion during labour and birth has become increasingly popular and widespread in many countries, in particular in midwifery-led care settings. Nevertheless, there is a dearth of quality data about waterbirth, with currently available findings mostly arising from observational studies and case series. The lack of high-quality evidence and the controversial results reported by different studies determined a "behavioral gap" without clearly objective, consistent indications allowing for a sound and evidence-based decision making process. Although water immersion in the first stage of labour is generally considered a safe and cost-effective method of pain management for women in labor, concerns still linger as to the safety of immersion during the second stage of labor and delivery, particularly in terms of neonatal risks and medico-legal implications.

Management of the active second stage of labor in waterbirths compared with conventional births - a prospective cohort study.

BACKGROUND: The management of the active second stage in labor and perineal protection varies between countries and is rarely described regarding waterbirths. The objective of this study was to describe how midwives manage the active second stage of labor in waterbirths compared to conventional births. A secondary aim was to compare clinical outcomes between the two groups. METHODS: A prospective cohort study, based on 323 women who gave birth at three clinics in Sweden, between Dec 2015-May 2019. The women were both primiparous and multiparous; 153 gave birth in water and 170 had a conventional uncomplicated birth. A protocol was completed by the attending midwife after birth, describing characteristics and management of the active second stage of labor as well as perineal protection. RESULTS: The active second stage of labor differed in several aspects between waterbirths and conventional births. Maternal pushing was spontaneous to a higher extent among women giving birth in water and the use of manual perineal protection was lower. The technique of manual perineal protection differed as well as birth positions. Giving birth in water was associated with less second-degree tears among primiparous women but with no differences among multiparas. CONCLUSIONS: In waterbirth, the midwife took the role of a more watchful attendee, making less interventions. Waterbirths were associated with less directed pushing and less manual perineal protection. However, there was still a widespread use of manual perineal protection, showing it is possible to use in the same way as in conventional births if needed.

Mindful awareness as a mechanism of change for natural childbirth in pregnant women with high fear of childbirth: a randomised controlled trial.

BACKGROUND: Mindfulness-Based Childbirth and Parenting (MBCP) is effective in increasing natural childbirth in pregnant women with high fear of childbirth (FOC) as compared to enhanced care as usual (ECAU). We aimed to examine through which pathway of action MBCP reaches this effect, based on a model of approaching or avoiding the challenges related to childbirth. METHODS: One hundred eleven pregnant women with high FOC were measured pre- and post-intervention on FOC (emotion pathway), catastrophic beliefs about labour pain (cognition pathway) and mindful awareness (attention pathway). A multiple mediation model was used to examine through which pathway the mechanism of change operated in relation to approach (i.e., natural childbirth) versus avoidance (i.e., self-requested caesarean section). RESULTS: It was found that greater mindful awareness (18% R2 = 0.18, F[1107] = 22.77, p < 0.0001) was the only significant mechanism of change operating through the attentional pathway leading to natural childbirth. More specifically, nonreactivity to inner experience (a facet of mindful awareness) showed to be the strongest mechanism of change. More extensive meditation practice was positively associated with natural childbirth; however, the number of completed MBCP sessions was not associated with the outcome. CONCLUSIONS: An increase in mindful awareness was the strongest mechanism of change for better adaptation to the challenges of childbirth. Decreases in neither FOC nor catastrophic beliefs about labour pain were identified as mechanisms of change. Additionally, the more one meditated, the more one was inclined towards a natural childbirth. MBCP enhances adaptation to the challenges of childbirth and less use of obstetric interventions in the presence of high FOC. TRIAL REGISTRATION: The Netherlands Trial Register (NTR; 4302 ).

Maternal and neonatal outcomes following waterbirth: a cohort study of 17 530 waterbirths and 17 530 propensity score-matched land births.

OBJECTIVE: Investigate maternal and neonatal outcomes following waterbirth. DESIGN: Retrospective cohort study, with propensity score matching to address confounding. SETTING: Community births, United States. SAMPLE: Medical records-based registry data from low-risk births were used to create waterbirth and land birth groups (n = 17 530 each), propensity score-matched on >80 demographic and pregnancy risk covariables. METHODS: Logistic regression models compared outcomes between the matched waterbirth and land birth groups. MAIN OUTCOME MEASURES: Maternal: immediate postpartum transfer to a hospital, any genital tract trauma, severe (3rd/4th degree) trauma, haemorrhage >1000 mL, diagnosed haemorrhage regardless of estimated blood loss, uterine infection, uterine infection requiring hospitalisation, any hospitalisation in the first 6 weeks. Neonatal: umbilical cord avulsion; immediate neonatal transfer to a hospital; respiratory distress syndrome; any hospitalisation, neonatal intensive care unit (NICU) admission, or neonatal infection in the first 6 weeks; and neonatal death. RESULTS: Waterbirth was associated with improved or no difference in outcomes for most measures, including neonatal death (adjusted odds ratio [aOR] 0.56, 95% CI 0.31-1.0), and maternal or neonatal hospitalisation in the first 6 weeks (aOR 0.87, 95% CI 0.81-0.92 and aOR 0.95, 95% CI 0.90-0.99, respectively). Increased morbidity in the waterbirth group was observed for two outcomes only: uterine infection (aOR 1.25, 95% CI 1.05-1.48) (but not hospitalisation for infection) and umbilical cord avulsion (aOR 1.57, 95% CI 1.37-1.82). Our results are concordant with other studies: waterbirth is neither as harmful as some current guidelines suggest, nor as benign as some proponents claim. TWEETABLE ABSTRACT: New study demonstrates #waterbirth is neither as harmful as some current guidelines suggest, nor as benign as some proponents claim. @TheUpliftLab @BovbjergMarit @31415926abc @NICHD_NIH.
